Recent Development on Electrode Materials for Reversible Solid Oxide Cells

The reversible solid oxide cell(RSOC) is an all-solid-state electrochemical energy conversion device that can achieve an efficient and clean reversible conversion of chemical energy and electrical energy. In anticipation, the RSOCs can be applied in the field of the intelligent electric grid for peak shaving, as well as the conversion and storage of large-scale renewable energy. As the key components of RSOCs, the electrode materials are expected to exhibit great performance and stability since the RSOC works in a reversible cycle both in solid oxide fuel cell(SOFC) and solid oxide electrolysis cell(SOEC) modes. There is an impetration to improve the catalytic activity and the redox stability of electrode materials. This paper briefly introduced the working principles of RSOCs, discussed the recent progress of electrode materials for RSOCs and the application of symmetrical electrode materials and prospected the future development direction for RSOC.
